Hi all just found this forum while trying to sort out the problem I have with my bathroom tiles, so I'm hoping that someone can point me in the right direction.
I have had my bathroom fully re-tiled with Atena Marble Gris tiles from Topps Tiles and then grouted in with swimming pool grout, all the work was done by a private tiler and not Topps Tiles.
The problem I have is with water/damp getting behind the tiles, it first appeared after the shower was used for the first time by the kids (teenagers) and was pointed out to me by the wife that some of the tiles around the top of the bath where going dark, it was obvious that it was water/damp getting behind the tiles and showing through the glaze so I allowed the tiles to dry out and had a shower myself and sprayed all the walls around the bath/shower area and found that almost all of the tile edges discolored in the same way some travelling a good 3” towards the centre of the tile. More evident around the top of the bath but it is all over see pics.

I have had the tiler back to see it and he says he’s not seen this before and was a bit bemused by it and could only come to the conclusion that the tiles where at fault (think I agree with him) and to get the manager from topps tiles in to have a look, this we did.
The manager arrived and asked to see the tiles, after spraying the tiles for a couple of minutes said that there was nothing wrong so the daughter had a shower and this then showed up the problem.
The manager then tried to pick fault with anything apart from the tiles, told me that the grout is not water proof and that the water will soak into the grout and then come back out!!!!!!!!, “if it’s good enough for swimming pools then surly it good enough for a shower”, also grout lines are a bit wide; no they’re not, the silicon runs was not wide enough “this does not explain how it happens in the middle of the wall’s”.
Finally the manager said that she would need to get grout, adhesive, silicon and tile specialists/reps in to have a look, I said fine by me and she went away with a spare tile in hand.
The next I heard was from an adhesive rep saying that the biscuit on the back and sides of the tiles is porous and that the glaze on the front is thin, Topps manager now wants me to pay for some water proofing to paint onto the grout, will this work as a permanent solution or should I stick to my guns and insist on the tiles being replaced at topps expense.
Thanks Colin.

Read the word marble, then read the bicuit of a tile meaning cerarmic.

Tile grouts are water resistent not waterproof

Hi whitebeam thanks for the info but what are you trying to tell me, marble is just the name of the ceramic tile also are you telling me that the biscuit is the tile or the coating on the front.

I would let them waterproof the tile grout and see how it goes from there but if it continues then get back to them.

asked to sort same problem out last year, I said it was the tiles but when a company makes millions of them thay are not going to admit it. I re grouted with mapei ultra colourplus and sealed it, damp still got in. The tiles even 'window framed' when I grouted the tiles!
Does the glaze wrap around the edge of the tile?
ps welcome to the forum

That is water ingression through the joints and needs sorting before it damages the substrate..

Leave to dry and use a grout sealer to help water run off..


Just a thought as well.. what adhesive was used..?

I have had this topps 8x8 bumpy whites, again due to the ceramic not covering the edge of the biscuit.

If the adhesive was cement based and the walls tanked there shouldnt be a problem. Do you know what adhesive was used and were that walls tanked?

:welcome: Colin.
The adhesive coverage might be affecting this too,
did your tiler serrate the wall or did he dot a dab the tiles?
The grout sealer mentioned above might work though,time will tell.
